Blink Sketch

In linux we can use the HardwareGPIO_RPI class: by default the device gpiochip0 is used. If you want to use another device, you can indicate it in the constructor of HardwareGPIO_RPI;

Here is the PulseView output of the Blink Sketch

SPI Sketch

In Linux we can use the HardwareSPI_RPI class: by default the device "/dev/spidev0.0" is used. If you want to use another device, you can indicate it in the constructor of HardwareSPI_RPI;

Here is the PulseView output of the SPI Sketch
